Abstract

SE DESCRIBE UNA COMPOSICION DE CERAMICA CONDUCTORA QUE CONSTA ESENCIALMENTE DE ALUMINA, CROMO, Y MAGNESIO, Y ES ADECUADA PARA USO COMO ELECTRODOS DIANA EN APLICACIONES DE CARGA DE FIBRA ELECTROSTATICA. SE DESCRIBEN CERAMICAS QUE MUESTRAN CAPACIDADES RESISTIVAS DE VOLUMEN DE 10{SUP,12} OHM-CM O INFERIORES A 20 (GRADOS) C, Y TIENEN EXCELENTE ESTABILIDAD ELECTRICA Y PROPIEDADES MECANICAS SUPERIORES; Y SE DESCRIBE UN APARATO DE CARGA ELECTROSTATICA QUE EMPLEA UN CONDUCTOR ELECTRONICO CERAMICO QUE TIENE UNA CAPACIDAD RESISTIVA DE VOLUMEN DE DESDE ALREDEDOR 1 X 10{SUP,7} A 5 X 10{SUP,10} OHM-CM Y UNA DUREZA DE AL MENOS 5 GPA.A COMPOSITION OF DRIVING CERAMICS THAT ESSENTIALLY CONSUMERS ALUMINUM, CHROME, AND MAGNESIUM IS DESCRIBED AND IS SUITABLE FOR USE AS A DIANA ELECTRODE IN ELECTROSTATIC FIBER CHARGING APPLICATIONS. CERAMICS DESIGNING RESISTIVE VOLUME CAPABILITIES OF 10 {SUP, 12} OHM-CM OR LOWER THAN 20 (GRADES) C ARE DESCRIBED, AND HAVE EXCELLENT ELECTRICAL STABILITY AND SUPERIOR MECHANICAL PROPERTIES; AND AN ELECTROSTATIC CHARGING DEVICE IS DESCRIBED THAT USES A CERAMIC ELECTRONIC DRIVER THAT HAS A RESISTANT VOLUME CAPACITY FROM AROUND 1 X 10 {SUP, 7} TO 5 X 10 {SUP, 10} OHM-CM AND A HARDNESS OF AT LEAST 5 GPA
